Regarding agent-less/connection-free backup/restore for Vmware

I know that NetBackup 7.5 can do agent-less backup, single file restore, application aware backup, however I still have the following questions:

1. Can we restore single file to its original location when there is no backup agent installed in VM? I thought the answer is no but just read Veeam release note and it cleaims that it can do it...

2. If we have agent-assisted application level backup, can we backup and restore without needing connection between NetBackup agent and Netbackup servers? again I thought the answer is no until I read Veeam release note and Veeam claims that it can "connection free" backup.

The result is powerful, easy-to-use and affordable backup that fully leverages the
virtual environment and eliminates the need for agents.

Direct file restore. When restoring a guest file back to its original location from the backup console
(Backup Browser), perform the restore with a single click. You no longer need to supply destination
information, and Veeam Backup & Replication does not have to stage the file locally on a backup server
or on a network share.

Direct file restore. Perform a direct file restore (described earlier) without a network connection
between the backup server and the destination VM.

I have always believed the reason why NetBackup or backup vendors can't do these because Vmware hasn't been able to provide such functionalities. What is confusing me is why Veeam cleaims it can do the magic...
